Air Source Heat Pumps

All you need is the air that you breathe.  Air Source Heat Pumps (ASHPs) can heat your home and provide hot water by extracting energy from the atmosphere around you.

ASHPs are relatively cheap to run so you could save money on your fuel bills, especially if you currently use oil.

You can also generate an income through the Government’s Renewable Heat Incentive (RHI), while at the same time lowering your carbon emissions.

If you currently have an oil-powered heating system, you will also benefit from no longer having to rely on fuel deliveries.

Like ground source equivalents, ASHPs use ‘fit and forget’ technology, which is very reliable and requires little maintenance.

ASHPs don’t require large areas of land, making them ideal for homes with smaller gardens. They are also easier to install than Ground Source Heat Pumps (GSHPs) because you don’t need to bury pipes in your garden to extract the heat.

As an accredited, independent installer, we offer the best advice to suit your particular circumstances. 

Pure Renewables are registered under the Microgeneration Certification Scheme, which means your system will be eligible for payments under the RHI. 

Our experts will provide you with clear information on all your aspects of your installation, including costs, and keep you fully informed throughout.

Healthy return
on investment

A typical ROI for a domestic ASHP would be around 10 per cent with a payback period of around 12 years.

ASHPs offer efficiencies of around 320 per cent compared to 400 per cent for GSHPs and 80-85 per cent for a boiler.

In order to maximise the benefits from an ASHP, your premises need to be well insulated to ensure they retain the heat generated, especially in winter.

Air Source Heat Pumps (ASHP) absorb heat from the outside air, in the same way that a fridge extracts heat from its inside. There are two main types of ASHP - an air-to-water system distributes heat via your wet central heating system, while an air-to-air system produces warm air which is circulated by fans to heat your property.

Air Source Heat Pumps are ideal for new-builds, or in a well-insulated existing property. You need space outside for a unit to be fitted, either on a wall or on the ground, where there is a good flow of air. The property should be well insulated and draught-proofed for best results and you will see better savings if replacing an electricity or oil heating system. 

The pump can get heat from the air even when the temperature is as low as -20° C. If temperatures plummet even further, the heat pump’s internal auxiliary unit will add the additional heat requirement.  ASHP come fitted with an auto-defrost function to ensure 100% efficiency, so they can continue to produce hot water and heating in all weathers.

ASHP technology has an Energy Efficiency Rating of A, which is the highest level for heating and water production.

How much you can save will depend on what system you use now, as well as what you are replacing it with. ASHP work best with underfloor heating or large radiators and are cheaper to run that oil-powered systems and older inefficient systems.  Our experts will explain how to control the system so you can use it most effectively.

The Renewable Heat Incentive (RHI) is Government incentive scheme to encourage the uptake of renewable heat technology among businesses and homeowners.

It covers a range of technologies, including ground to water heat pumps, air to water heat pumps and solar thermal panels. Air to air heat pumps, are not supported by RHI.

The Non-domestic RHI was launched first in November 2011 to provide payments to industry, businesses and public sector organisations. The Domestic RHI was launched in April, 2014, and is open to homeowners, private landlords, social landlords and self-builders.

RHI cash payments are made quarterly over seven years. The amount you receive will depend on a number of factors - including the technology you install and the latest tariffs available for each technology.

Our guarantees last up to five years and systems are expected to operate for 20 years or more.

They may be considered Permitted Development, in which case you will not need planning permission, but it is always a good idea to check with your local planning office.

ASHP are much quieter now than even just a few years ago. Carefully sited pumps should present no disturbance to you or your neighbours and we have to follow MCS noise emission standards which require careful emission calculations.
